Sites speed and efficiency are really important for users. If your site is too slow, you will lose not only visitors, but potential clients too. Search systems, e.g. Google, take into account the web-site’s speed in the search rating, that’s why you should take everything into account during optimizing. Every millisecond is included. Here you will see several main offers concerning efficiency optimizing.

Postpone the content loading, if there is such opportunity

Site Speed Optimizing Tip 1:Ajax allows us to build web-pages which can be refreshed at any time asynchronous. It means that instead of refreshing the whole page we can refresh just the part of it. We can use the image gallery as an example. The image files are large and heavy; they can slow down the web-pages loading. Instead of loading all images, you can just show to the user, who comes to the page for the first time, the tiny copies of them. If the user wants to see only several images, he mustn’t wait for loading all of them. This development patters is called “lazy loading”.

Use separate JS and CSS files

Site Speed Optimizing Tip 2:When user loads your web-page for the first time; the browser caches external resources, as JavaScript and CSS files. So, it is better to put them outside the pages. Using of built-in CSS is also increases the rendering time of the page; by identifying everything in the main CSS file you allow browser to do less job during page rendering.

Use caching systems

Site Speed Optimizing Tip 3:If you think that your site connects with data base every time in order to make one and the same content, it is time for using caching system. If the caching system exists your site will have to create content only once instead of creating it every time the users visit the page. Don’t worry; caching systems periodically refresh their caches irrespective of your adjusting, so even the constantly changing pages can be cached.

Such popular content administrative systems as Drupal and WordPress have static caching, which transforms dynamically generated pages into static HTML files.

Avoid images sizes changing in HTML

Site Speed Optimizing Tip 4:If the image is primarily 1280×900 px but you need it to be 400×280, you should change the sizes and save the image again using the image editor, instead of using attributes of width and height in HTML.

Don’t use images for showing the text

Site Speed Optimizing Tip 5:It will make the text on image not only inaccessible for screen readers and fully useless for SEO, it even will increase the time of page loading.

Load JavaScript in the end of the document

Site Speed Optimizing Tip 6:It will be better if your scripts load in the end of the page. It allows browser to render everything before loading JavaScript. Due to this your pages will be more responsive, because the JS’s work principle is to block everything while it is loading.

Use Content Delivery System

Site Speed Optimizing Tip 7:Your site’s speed is under the influence of the users’ location relative to the web-server’s location. The farther they are, the longer distance should information overcome. If you have a cached content on several strategically based geographical locations it will help you to avoid such problem.
